Memory IC Procurement Notes

Verify the specific ordering suffix 'GY' corresponds to the SOP-8 208mil package configuration as defined in the manufacturer's ordering information section. Confirm that the required voltage range aligns with the 2.7V to 3.6V specification. Ensure compatibility with the host system's SPI controller regarding clock frequency limits and command set support. Check for any special order requirements regarding reset pin configurations if using alternative packages.

Memory IC Selection Notes

Select this component when a 128M-bit density is required with a single 3V supply voltage. It is suitable for designs needing uniform sector erase sizes for simplified file system management. Consider this part for applications prioritizing low power consumption in standby modes. Verify that the SOP-8 package dimensions fit the PCB layout constraints. Ensure the design accounts for the default Quad Enable bit state which facilitates high-speed quad operations without additional configuration steps.
